Raced a friends FBO 335i last night (member "Stucks" here on e90post). Cars are pretty much identical except I have 6MT and Stucks has 6AT. Also, the tune is different. I am Cobb Tuned (Protuned by Jake aka FlyLow335i) and Stucks is JB4 Tuned (Map 5). His car pulls away when I shift from 2nd to 3rd and increases the gap when I shift from 3rd to 4th. The lesson here is that I need to shift FASTER next time

Just curious, is your car bogging between shifts? Also, from what I've learned with racing other N54's that were AT's and DCT, the only way you will keep up is from 3rd gear 60 roll. The 2-3 shift kills the 6mt no matter how fast you shift. The gear spread is too large, and if you do shift fast you'll just bog.

I have BMS clutch stop, BMS modified clutch valve, and B&M short shifter.

I agree with you that the 6MT's do better from a 60 roll. When we do another run, we will do a 60 roll. As for bogging, no I don't think so.

It's the shift killing the race -- The car clearly has a "delay" as Laid_Black has to cross the gate going from 2nd to 3rd gear (~39 seconds into the video).

Obviously 2 cars with the same mods & transmissions (b/c of the gearing difference) would give the best representation of which tune can give more. BUT at the end of the day, who really cares though (unless you're tracking your car)
